THOMAS JAMES DAVIS, OF BROOKLYN, NEW YORK.

GOLF CLUB.

Application filed December 29, 1923: Serial No. 683,412.

\ carry through, the attack upon the ball.

It is well known that the so termed carry through is'exceedingly important and .yetdifficult of attainment. The amateur or student starts the-club from the shoulder with certain vim and velocity but as the club approaches the ball, the head of the club is slowed down until the contact is at a force less than that desired. The swing is neither complete nor artistic and this so' called choking of the stroke is noticeable even in players of long experience, the choking ousness or overanxiety.

To encourage a carry through is then the object of this invention and the follow ing is what I consider the best means of car-, rying out this invention and the accompanying drawing should be referred to for a complete understanding of the specification which follows In the drawing 1 Fig. 1, is a sectional, plan view of a golf club, commonly termed a driver.

Fig. 2, is a vertical, sectional view.

Fig. 3, is a perspective view of the driver.

Fig. 4, a sectional, plan view of a modification.

Similar reference numerals indicate like parts in all the figures where they appear.

The handle or staff of my club is of ordinary length, shape and contour and I therefore show but a small fraction of the staff as indicated at 1.

The club head should be made of wood and may or may not be metal faced. The shape of the head and the facing are not in my invention changed from the ordinary and well known standards. The head is provided with a stem as shown at 2, to which the staff of handle is secured, by any suitable means, such as the mousing cord 3.

Within the head and quite local to the impact face 4 of the club, I produce a well 5 resulting most often from nervand connected with the well is a channel 6, which extends the length of the club head, continuing upward into the stem 2, as shown at 7. The well and channel must be water tight and I therefore place a plate 8 over the well as shown in Figs. 2 and 3. Thechannels or canals inthe head may be formed by boring and if bored in the general manner shown, plugs 9 and 10 are incanal, which it was necessary to produce to give the canal the proper angle andsa plug or dowel 11, secured to or formed integral with the shaft or staff 1 enters that part 7 of the canal which is produced in the stem 2.

Before describing the function of the well and connecting canals, I will describe the construction as shown in Fig. 4.

Here the club is divided at approximately mid-height and with a routing tool the canal 12 and well 13 are produced. The boring tool may produce the canal 12 in the stem 2. One-half of the canal 12 and well 13 may be produced in each the bottom and top halves of the head and when the two parts of the head are secured together, a cylindrically shaped canal and suitably shaped well are produced. The two parts of the club head may be secured by means of screws 15, but should be also cemented together, so that the canal and well will be water tight.

As shown by the dotted line 16, the channel may be continued into and even through the shaft or handle, thus providing greater travel for the mercury.

The length of travel will be determined by the speed of travel of the mercury, 'it being the" desire that the mercury reach the face of the club at the time that the face reaches the ball.

Into the canal and well, I place metallic mercury, the quantity used being that quantity which will be contained almost fully within the well. The mercury can readily pass through the channels or canals and when the club is lifted, the mercury will be wlfolly/within the stem 2. The downward movement of the club, in making a stroke will cause the mercury to rush into the well, encouraging the user of the club to continue the swing to its, full extent.

Other modific ations may be made within the scope of the appendedclaims without departing from the principle or sacrificing the advantages of the invention.

Having carefully and fully described my troduced toclose the continuations of the I invention, avhat I claim and desire to obtain is 1. A head for golf clubs provided with a channel, a portion of which extends parallel with the face and aportion of which is at right angles to tlie'face and a movable mem her in said channel, adapted to approach the face of the head, during the stroke, said movable member comprising metallic merry. 2. A golf club having a head and a handle,

both of which are provided with a channel,

a portion of which extends parallel with the face of the club and-a portion of which is at right angles to the face and a movable member in said channel, adapted to approach the face of the head, during the stroke, said movable member comprising a metal in semiliquid form. I

3. A head for golf clubs provided with a channel, a portion of which extends, parallel with the face and a portion of which is at right angles to the face and a movable member in said channel, adapted to approach the face of the head, during the stroke, said channel being of cylindrical form and havipg a well of greater diameter adjacent the ace.
